Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reminder applications lack the ability to issue alerts based on the proximity of two or more paired devices, limiting their effectiveness for tasks that require users to be in close physical proximity to each other.
Innovation Solution
A proximity-based reminder system that uses a wide-area network to detect the distance between paired devices and issues alerts when they come within a predefined proximity, utilizing a combination of GPS data, cellular triangulation, and short-range communication methods like Bluetooth to confirm proximity and trigger reminders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing reminder applications use GPS data or time-based triggers, then they can provide location-based or scheduled reminders, but they cannot effectively trigger reminders when multiple devices are in close proximity for face-to-face interactions
Solution Approach 1:
The patent combines multiple proximity detection methods (GPS data, cellular triangulation, and Bluetooth) into a unified reminder trigger system. This merging allows the system to leverage the strengths of each method: GPS for broad location tracking, cellular triangulation for intermediate range detection, and Bluetooth for precise close-proximity confirmation, thereby enabling versatile face-to-face interaction reminders.
Solution Approach 2:
The reminder application is enhanced with multi-functional proximity detection capabilities that work across different scenarios. The system can trigger reminders based on various conditions including GPS location, cellular network proximity, and Bluetooth device detection, making it universally applicable for different types of face-to-face interaction reminders regardless of the specific context or distance involved.
2Measurement precision
If the system uses multiple proximity detection methods (GPS, cellular triangulation, Bluetooth), then proximity detection accuracy improves, but system complexity increases
Solution Approach 1:
The proximity detection system is segmented into distinct functional layers: GPS-based location tracking for broad area detection, cellular triangulation for intermediate range proximity detection, and Bluetooth for precise close-proximity confirmation. Each layer operates independently with its own detection logic and trigger conditions, allowing the system to achieve high measurement precision while managing complexity through modular, segmented architecture.
Solution Approach 2:
The system performs preliminary proximity assessment using less resource-intensive methods (GPS and cellular triangulation) before initiating more complex Bluetooth scanning and pairing verification. This preliminary action filters out cases that don't meet basic proximity criteria, reducing the computational burden of detailed Bluetooth-based detection and overall system complexity.
3Reliability
If the system requires Bluetooth pairing verification, then false positive reminders are reduced, but the time to process proximity detection increases
Solution Approach 1:
The system implements partial verification by using Bluetooth connection status and pairing history as preliminary checks before full verification. If devices are already paired or have recent pairing history, the system can trigger reminders with reduced verification overhead. Full Bluetooth pairing verification is performed only when necessary, balancing reliability with processing time efficiency.
Solution Approach 2:
The system uses feedback from Bluetooth connection status, pairing history, and signal strength measurements to dynamically adjust verification requirements. When feedback indicates high confidence in proximity (strong signal, established pairing), the system can reduce verification time. When feedback is ambiguous, more thorough verification is performed to maintain reliability.

AI summary
A proximity-based reminder system includes one or more proximity detectors for determining whether a distance between two or more paired electronic devices satisfies various criteria. Data transmissions across a wide area network (WAN) are used to determine whether a distance between paired devices satisfies a first proximity condition. Transmissions across a local area network (LAN) are used to determine whether the distance between the paired devices satisfies a second proximity condition. When the first and second proximity conditions are satisfied, the proximity-based reminder system issues a reminder alert notification to one or more of the paired devices.
